Default how to determine how much injector im using?

the data log shows the term "Inj PW" what exactly does this mean? the injectors are stock 6 liter injectors witch im sure are 36 lbs/hr and the "Inj PW" says that im at about 23 on the "Inj PW" scale at 6000rpm when i shift. so does this mean im only using 23 lbs/hr at WOT at 6000rpm? im trying to determine this because i want to know if i can switch to e85 and still use the stock injectors. keep in mind the motor is completely stock

doesn't your datalog show duty cycle?

PW = pulse width, its the amount of time in milliseconds the injectors are being opened

yea i just found it at the highest point it said duty cycle was 89.9% im guessing that means im using 89.9% of my injectors and that ill have to get new ones for e85?

yes that means your using 90% or your injectors capacity. You typically need about 30% more for E85 so you will definitely need bigger ones.
